Subject: [PATCH wireless-next v2 6/6] crypto: Remove michael_mic from crypto_shash API
Date: Tue, 7 Apr 2026 20:06:51 -0700 [thread overview]
Message-ID: <20260408030651.80336-7-ebiggers@kernel.org> (raw)
In-Reply-To: <20260408030651.80336-1-ebiggers@kernel.org>
Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used. Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.
It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.
